After reading the game manual and consulting Question and Answers, there still remains a question regarding rule G12 (the definition of possession) on our team. As answered to Q82, sticking an appendage in front of the low goal in attempt to block is not illegal. The question that arises is if a robot is trying to push a ball into a low goal but a defensive robot is in the way so that the offensive robot continues to push the ball no where, is the considered "trapping" thus penalizing the defensive robot? Trapping is defined as: "overt isolation or holding one or more BALLS against a FIELD element or ROBOT in an attempt to shield them". Is the defensive robot HOLDING a ball against a ROBOT? And what are they meaning when they say shielding?
